Abstract (en)
[origin: EP0908685A2] Flue gases are introduced into water via a diving bell submerged in the top region of the vessel. A heat exchanger is linked to different heights in the vessel wall. Water (4) is heated inside a non-pressurised vessel (2) which contains an immersed diving bell (6). Liquid fuel is burnt inside a combustion chamber (8) and flue gases exit the burner (10) to enter the diving bell and then leave through an exit region (12) of the diving bell to enter the water, resulting in it being directly heated. A distributor plate (14) is provided at the diving bell exit to ensure good distribution of flue gases in the water. The diving bell is immersed only in the top region of the liquid so that layers of water with different temperature are formed. A heat exchanger (24) is connected to the vessel wall at different heights corresponding to different temperature layers. Useful heat is effectively recovered from flue gases.
